Converting into Earth Years:
Period; 1.69150 days divided by 365=0.004634327 (So this is my P)

Converting radius in AU:
Amplitude; 2.8674 into 1050= 0.002730857 (And this is my A)

Then take A^3= 0.00000002

Then take P^2= 0.000021477

Then take A and P and divide it, which equals to= 0.000948251 (Which I suppose is M?)

Ok up until now do you think I’m right? And these are the next steps one guy told me to do not sure if it’s right or not.

Take the answer of 0.000948251 and multiply it with the mass of sun, 2x10^30. Which equals to = 1.89650283 to the power of 27.

Then take that number and multiply it with 10^27, which equals to 1.89650283^54.

So is my answer then the last one? And here's the question Im being asked: If your answer is 2.0, your calculations say Jupiter is twice as massive as the Sun, if you get 0.005, then Jupiter is 1/200th of the mass of the Sun. Does your answer make sense?

Hi,

I have an 8" Celestron SCT and I just bought a Celestron Astro Solar Filter. I was pretty disappointed the first time I used it because I wasn't able to see any detail in the Sun at all. I could only see the Sun as a white circle. I used different eyepieces to vary the magnification from 50x-300x and still no definition at all. No swirling, no lines, no spots. Nothing. Just a white circle.

Is there a better filter that I could get that would show more definition?

What's the formula for finding the sum of a sequence of squared numbers?
such as,
26^2+27^2+28^2+...100^2

DO NOT give me the formula where the first number is one!!!!! that's what I keep finding when surfing the web for it.

But when new matter is "created" *Yes it can be if I am correct, because when we create antimatter we would have to create matter.* Does it just instantly have gravity, or is it possible that the gravity takes TIME to reach out?

If so, what if it's possible that "gravity" is faster than light? So fast we could not measure it?

If I wish to use the eigenvalue or real symmetric matrix as term project for numerical analysis for senior undergraduate, which size of the matrix should I restrict the original matrix? In the sense that it will not be too hard nor too easy. Also should I restrict the original matrix to be sparse. The required implementation language will be C++.
